Description
Technical Field
The utility model relates to the technical field of oral cavity cleaning, in particular to a toothbrush containing an antibacterial coating.
Background
In recent years, attention has been paid to the importance of oral health, and toothbrushes are an indispensable tool for cleaning teeth in daily life to clean teeth and oral cavity. Its main function is to remove food residues, bacteria and plaque from the tooth surface. The bristles of a toothbrush can effectively clean various surfaces of teeth by brushing the teeth. However, during brushing, the bristles are easily contaminated with bacteria in the mouth, especially when moisture remains on the bristles, which further promotes the rate of bacterial proliferation. After brushing, the toothbrush is exposed to the environment during storage and comes into intimate contact with bacteria in the environment, such as bacteria in the air, bacteria in a sink, and the like. Therefore, in order to prevent the toothbrush from being polluted by bacteria, the toothbrush should be washed with clean water for a plurality of times after brushing teeth, and the toothbrush should be placed in a place with good illumination and ventilation to dry the excessive moisture so as to avoid the rapid propagation of bacteria.
In daily life, people generally rinse the toothbrush roughly after brushing teeth, and place the toothbrush in a dark, window-away and moist environment in a bathroom in a wet state, so that the bristles are easy to grow bacteria and are polluted by the bacteria in the environment. According to studies, it was shown that more than 700 bacteria including Streptococcus stomatitis, streptococcus parahaemolyticus, haemophilus parainfluenza, enterobacter, escherichia coli, pseudomonas aeruginosa, helicobacter pylori, etc. were contained on the used toothbrush, wherein bacteria causing caries, periodontitis, halitosis oral problems also exist on the bristles, affecting our oral health.
Although people can change toothbrushes in three months generally, bacteria can reproduce faster, and long-term use of toothbrushes rich in bacteria for brushing teeth can cause oral health problems. Polymer materials such as polypropylene, polyethylene and the like have been used in the past where bristles contact the handle. The material has the advantages of relatively low price, small molding difficulty, easy surface modeling design and the like. However, the composition is easily affected by external factors such as ultraviolet rays and temperature, is easy to deform and age, and has no antibacterial effect. Meanwhile, the main chain of the polyethylene contains polar ester groups, so that the hydrophobic property of the polyethylene product is poor, the self-cleaning effect of the polyethylene product is limited, and therefore, the opportunity is provided for bacteria propagation.
The prior art in China considers the problem that the toothbrush bristles are easy to be polluted by bacteria, and mainly solves the problems that a sterilizing device specially designed for toothbrushes is used for sterilizing toothbrushes, the antibacterial toothbrush bristles are invented, an antibacterial plate is arranged in a toothbrush handle to generate electronic sterilization through illumination and bioelectric current, and the like, however, the problem of cost increase is caused, and most people do not use the toothbrush sterilizing device, the toothbrush with the antibacterial toothbrush bristles and the toothbrush which uses bioelectric current generated after human body contact to excite the electronic sterilization based on the currently collected data and information, and the factors such as price, convenience in use, biological safety of products and the like are considered.
